A mention rate on its own answers "did AI name us." Share of voice answers the more useful follow-up: "if not us, then who, by name, every time." That second number is what turns a visibility gap into an actual competitive map.
Why the specific names matter
An AI answer that recommends a category leader instead of a given business is not a vague miss, it is a named, repeatable pattern: the same one or two competitors tend to get cited across most of a category's buyer questions. Kelriva's AI Visibility Score logs the exact competitor names cited in place of a business across 8 real questions, rather than a generic "you are not visible" verdict with nothing to act on.
What to do with it
Once the specific competitor and the specific question are known, the fix is concrete: closing whatever content or citation gap is letting AI models treat that competitor as the default answer, the same "one gap, one fix" logic behind Generative Engine Optimization generally.
